No full textIn the second half of the XIII century, the Commune of Milan was lead by the “pars populi” and the family della Torre. They opposed Ottone Visconti and other rival nobles (“pars nobilium”) that had been exiled from the city and were living in the surrounding countryside (contado). In order to better contrast their rivals, the family della Torre decided to acquire the lands and the rights (“honor et districtus”) over several countryside places, including the village of Trezzano sul Naviglio. The policy of the family della Torre in the countryside is here investigated by the mean of three documents from the archive of the Canonica of S. Ambrogio of Milan. The help given by the Canonica was fundamental to the consolidation of della Torre’s hegemonic power in Trezzano sul Naviglio and more generally in the countryside
Giudicati e signorie : due percorsi di potere a confronto
No full textRiassunto: Nel XIII secolo entra in crisi
l’istituzione dell’Impero: il potere politico
di cui esso è depositario si frantuma in poteri limitati e particolari. In questo lavoro voglio mettere a confronto due percorsi di potere locale: da una parte la signoria della famiglia della Torre a Milano, una delle prime in Italia, punto di arrivo della lotta contro l’Impero per le
libertà comunali; dall’altra i giudicati della
Sardegna, istituzione derivante dalla dissoluzione
dell’Impero Bizantino nell’isola.
Di tutti e due esamino le modalità
dell’acquisizione del potere, il contesto in cui hanno operato, il rapporto tra città e contado, la funzione del “popolo” nell’attribuzione del potere, la necessità di una legittimazione da parte dell’autorità imperiale.
Abstract: In the 13th century the Empire
as political institution was in a state of
crisis. The Holy Roman German Empire
and the Byzantine Empire were reshaped
by extensive fragmentation into regional
districts with political autonomy, resulting
in a more limited influence for both emperors.
Here, I have compared two different
paths toward local power, the “Seigniory”
and the “Giudicati”. The Seigniory of the
family “della Torre” over Milan was one
of the first in Italy and is a paradigm of
acquisition of political autonomy within
the Holy Roman German Empire. Conversely,
the “Giudicati” were local kingdoms
that arose in Sardinia from the decay of
the Byzantine Empire. I discuss the ways
by which these regional political institutions
arose, their recognition by the emperor,
the context in which they acted, the
relations between city and peasantry, the
role of the “people” in awarding the powe
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
